This is meteorological data. This data set contains hourly or 3-hourly surface weather observations that are taken primarily at major airports and military bases. The stations are operated by the US National Weather Service (NWS), US Air Force Air Weather Service (AWS), U.S. Navy, and the US Federal Aviation Administration (FAA). The NWS and FAA sites are located in the US, Puerto Rico, Guam, American Samoa, and several other Pacific locations. The U.S. Navy and U.S. Air Force operate weather observing stations at military bases worldwide. Observations are made by trained personnel, or by automated equipment that has been tested by the controlling agency. Stations are usually fully instrumented and therefore record a complete range of meteorological parameters. Observations are generally recorded for the 24-hour period midnight to midnight. Basically, the major parameters are clouds, visibility, winds, air temperature, sky cover, relative humidity, air pressure, and present weather. However, there have been several historical changes in the way observations have been recorded, including the advent of the Automated Surface Observing System (ASOS) in 1992. The detailed parameters, allowing for such changes, are: sky condition in tenths and height per layer; sky condition in eighths and height per layer; altimeter setting; sky condition in tenths and cloud coverage by layer; sky condition in eighths and cloud coverage by layer; ceiling height; cloud type and height by layer; total amount of sky cover by the first two cloud layers and by the first three cloud layers; dew point temperature in tenths Celsius; dew point temperature in Fahrenheit; horizontal visibility; station pressure; present weather code; present weather between 5 and 10 statute miles in vicinity; relative humidity; sea level pressure; air temperature in tenths Celsius; air temperature in Fahrenheit; wet bulb temperature in tenths Fahrenheit; total sky cover in eighths; total sky cover and total opaque sky cover measured in tenths; wind direction and speed to 16 points; wind direction and speed; and wind direction and speed from ASOS. All parameters are not reported by all stations. The oldest data is in manuscript form. Older manuscript data is added to the archived digital data set from time to time; the earliest digital data is currently from 1936.Users must be aware that DSI-3280 and DSI-3283 (C00365) are similar. The only difference is that DSI-3280 contains quality controlled data that has been hand checked by personnel at the National Climatic Data Center. DSI-3283 only contains data that is automatically quality controlled, therefore, it is considered to be raw data. To make a wide range of climatic data available to researchers and the public. data set C00215 AEROVANES ALTIMETERS ANEMOMETERS AWS > AUTOMATED WEATHER SYSTEM BAROMETERS DRY BULB THERMOMETERS HUMIDITY SENSORS HYGROMETERS PRESSURE SENSORS PYRANOMETERS RAIN GAUGES TEMPERATURE SENSORS THERMOMETERS VISUAL OBSERVATIONS WET BULB THERMOMETERS WIND VANES WEATHER STATIONS ASOS > Automated Surface Observing System National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce 19360101 Present Ground Condition In work As Needed -180.0 180.0 90.0 -90.0 ISO 19115 Topic Category climatologyMeteorologyAtmosphere 004 elevation 006 DIF Discipline Keyword Thesaurus Earth Sciences > Atmosphere > Meteorology Earth Sciences > Atmosphere > Weather Earth Sciences > Atmosphere > Climatology Earth Sciences > Land > Hydrology GCMD Sciences Keyword Valids EARTH SCIENCE > SOLID EARTH > VOLCANOES > VOLCANIC ASH/DUST EARTH SCIENCE > ATMOSPHERE > AIR QUALITY > VISIBILITY EARTH SCIENCE > ATMOSPHERE > ALTITUDE > BAROMETRIC ALTITUDE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > CYCLONES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > FOG EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > HURRICANES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > LIGHTNING EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > STORMS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > TORNADOS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > TYPHOONS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > MAXIMUM/MINIMUM TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ALTITUDE > STATION HEIGHT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > ATMOSPHERIC PRESSURE MEASUREMENTS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > PRESSURE TENDENCY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > DEW POINT TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > HUMIDITY EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD BASE EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD CEILING EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD HEIGHT EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD AMOUNT/FREQUENCY EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD TYPES EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD VERTICAL DISTRIBUTION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION AMOUNT EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION RATE EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SNOW EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > FREEZING RAIN EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SLEET EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > HAIL EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > RAIN EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SOLAR RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > WIND TENDENCY GCMD Location Valids GLOBAL LAND GCMD Location Valids TROPOSPHERE LAND SURFACE Automated Surface Observing System ASOS AUTOMATED WEATHER SYSTEM AWS WEATHER STATIONS ANEMOMETERS WEATHER STATIONS ALTIMETERS WEATHER STATIONS BAROMETERS WEATHER STATIONS DRY BULB THERMOMETERS WEATHER STATIONS HUMIDITY SENSORS WEATHER STATIONS HYGROMETERS WEATHER STATIONS PRESSURE SENSORS WEATHER STATIONS PYRANOMETERS WEATHER STATIONS RAIN GAUGES WEATHER STATIONS TEMPERATURE SENSORS WEATHER STATIONS THERMOMETERS WEATHER STATIONS VISUAL OBSERVATIONS WEATHER STATIONS WET BULB THERMOMETERS WEATHER STATIONS WIND VANES WEATHER STATIONS AEROVANES 1 None None Unknown Completeness information not available.
